Is nacl deprecated in favor of the libsodium fork? Or are both projects strong and continuing in parallel?

  [libsodium] is a portable, cross-compilable, installable, 
  packageable fork of NaCl, with a compatible API, and an 
  extended API to improve usability even further.

I see DJB (original nacl creator http://nacl.cr.yp.to/) appears to contribute to libsodium: https://github.com/jedisct1/libsodium/blob/master/AUTHORS

The website for nacl seems to be a bit outdated (many dates seem to refer to 2013), although there is still this tantalizing bit about features in the 'next' nacl release:

  Major features in the next release of NaCl: full PIC support, 
  for easy integration into other languages; Ed25519 signatures 
  (currently available in SUPERCOP); NEON optimizations.

Thanks for any help clarifying this.
